Psychology Tricks That Work on Anybody

  1. If you want your kids to eat broccoli, ask them if they want 2 broccoli stalks or 5, instead of just asking them if they want broccoli. This way you’ve already made the choice for them, but they’ll feel like they’re getting a great deal by choosing the amount of broccoli they want. You can expand this trick to other situations, too.
  2. To have a little fun with words, when having a conversation with someone, pick a word they say and then each time they say the word, or words close to it, smile, nod or give some type of positive affirmation, and watch them say the word all the time.
  3. Do you have a song stuck in your head that you’d like to forget? Think of the end of the song. According to the Zeignark effect, your mind tends to think of things left unfinished, so thinking of the end of the song will close the loop and allow you to get the song out of your head.
  4. To know if someone is interested in a conversation look at their feet, if they are pointing towards you, they are. If they are pointing sideways or any other direction, they aren’t.
  5. Ever get the feeling that someone is watching you, but you’re not sure? Try yawning and then glancing at your suspected stalker. If they yawn, then you know they’ve been watching you, since yawning is contagious.
  6. If you want people to take you seriously, tell them what you say is what your father taught you. People tend to believe fatherly advice inherently.
  7. Crack a joke and observe the people who are laughing around you. People who feel close to each other will be looking at each other. This is useful for discerning out friendships and other relationships.
  8. In crowded areas, look in the direction in which you intend to go and watch the walkway just open up. In busy areas and crowded streets, people tend to watch other people’s eyes to see which direction they will go so they can go the opposite way.

How Much You Should Tip For Every Service?

  1. Tip waiters 15-20%, because big part of their salary is exclusively from tips (can be over 90%).
  2. Baristas – Tip is not necessary, but a little money under a dollar is always nice. If the service is very nice you should consider a tip above $1.
  3. Bartender’s salary highly depends on tips too. Give more tip if the drink you buy takes more time to make (like cocktails).
  4. Cab drivers like tips too, which should be above 10%.
  5. Food delivery is not the highest paying job and you should tip the delivery guy 10-20% depending on how much time it took for your food to deliver and how bad is the weather.
  6. Restaurant takeout – If the food is nicely made and looks delicious tip $0.5-$1, but this is not always necessary and not a rude thing not to tip.
  7. Barbershop – If you like your new hair after a haircut give a nice 20% tip to the barber. The same applies to beauty salons.
  8. The above numbers applies to USA or Canada. There are countries where tipping is not necessary or not usual. Check out this or this infographic about how tipping is working in different countries.
